This thesis describes several approaches evaluating the resistance of cement-based composites under adverse external-sourced sulfate attack. The conventional approach of evaluation by means of measuring expansion was discussed in comparison with the sulfate diffusion, which was quantified as a...

Strands and wire ropes are widely used in many civil and mining engineering applications, such as encountered in cable stays for bridges, suspension bridge elements, mooring structures, cranes, ropes for shovels, draglines, and for elevators and mine shaft cages and skips. These ropes are broadly

Coped beams are susceptible to fatigue cracking in the web at the cope radius when subjected to tension in the coped region. Use of an adhesively bonded composite patch over the crack can reduce the stress concentration and delay further crack growth. This report contains the results of a full

This study is part of a joint Canada-India research program to effect sustainable construction. Alberta generates a significant amount of waste from agricultural- and forest-based industries. Similarly, India has lots of sugar cane bagasse waste. Researchers in both countries want to use these...

The current design practice is to ignore the interaction between masonry infill walls and containing frames due to the inadequate and incomplete guidance in current codes and standards. Most investigations on the behaviour of masonry infill shear walls were performed on scaled specimens and...

structural collapse. As such, this study focuses on spar cab-shear web debonding by comparing the dynamic behaviors of WTBs with and without debonding via finite element simulations, aiming to shed light on vibration-based damage detection for WTBs. Specifically, this study performed debonding and vibration

environment are highly susceptible to various corrosion-induced deteriorations, which can in turn affect the structural behaviour of PC girders. Therefore, it is important to understand and quantify the corrosion effects on the flexural and shear behaviours of PC bridge girders. In parallel with the

then used to conduct comprehensive parametric studies for both flexural and shear critical girders, respectively, focusing on the corrosion effects on the structural behaviour (e.g., stiffness, residual strength). The deterioration features considered in the parametric studies include pre-stress loss

Fatigue cracking is one of the major integrity threats to oil and gas pipelines. Having a reliable trajectory of fatigue crack growth once detected is very crucial for decision making regarding integrity threat management. In-line Inspection (ILI) tools, and other non-destructive methods are used...

Prestressed concrete (PC) bridges are a major component of North America’s transportation network. As this network ages, the response of deteriorated PC bridge girders is of interest since rehabilitation and repairs are constrained by limited infrastructure budgets. Bridges are often evaluated...
